The coating comprises a first coating portion between load bearing members next to each other, and a second coating portion forming an outer side of the rope facing in thickness direction of the rope, and in that the material of the first coating portion is substantially harder than the material of the second coating portion. ## Claims ### Claim 1 A rope arrangement, comprising: a belt-shaped rope substantially larger in a width direction than a thickness direction thereof, the belt-shaped rope including, two or more load bearing members, and a coating embedding the two or more load bearing members therein, the two or more load bearing members oriented to extend parallel with a longitudinal direction of the belt-shaped rope such that a gap is formed in the width direction between adjacent ones of two or more load bearing members, the coating extending into the gap, the coating including, a first coating portion between the adjacent ones of the two or more load bearing members, the first coating portion including a first material, and a second coating portion forming an outer side of the belt-shaped rope facing the thickness direction, the second coating portion including a second material that is substantially softer than the first material; and a crowned rope wheel including a crowned circumferential surface such that end diameters thereof are smaller than a central diameter thereof, the crowned rope wheel having the belt-shaped rope passing therearound such that the second coating portion forming the outer side of the belt-shaped rope rests against the crowned circumferential surface of the crowned rope wheel, wherein the first coating portion is made of a material having a first Shore A hardness, and the second coating portion is made of material having a second Shore A hardness, wherein the first Shore A hardness is more than Shore A 85. ### Claim 2 (depends on 1) The rope arrangement according to claim 1, wherein the first coating portion between the adjacent ones of the two or more load bearing members is bonded with both of the adjacent ones of the two or more load bearing members to couple the adjacent ones of the two or more load bearing members. ### Claim 3 (depends on 1) The rope arrangement according to claim 1, wherein the first coating portion between the adjacent ones of the two or more load bearing members is a solid one-piece structure extending between the adjacent ones of the two or more load bearing members throughout their lengths. ### Claim 4 (depends on 1) The rope arrangement according to claim 1, wherein the belt-shaped rope is configured to be guided by the crowned circumferential surface of the crowned rope wheel. ### Claim 5 (depends on 1) The rope arrangement according to claim 1, wherein each of the two or more load bearing members is substantially larger in the width direction of the belt-shaped rope than in thickness direction of the belt-shaped rope. ### Claim 6 (depends on 1) The rope arrangement according to claim 1, wherein each of the two or more load bearing members is shaped to have at least one planar side face. ### Claim 7 (depends on 1) The rope arrangement according to claim 1, wherein the two or more load bearing members is made of a composite material including reinforcing fibers embedded in a polymer matrix, the reinforcing fibers being carbon fibers or glass fibers. ### Claim 8 (depends on 1) The rope arrangement according to claim 1, wherein the first coating portion is completely encapsulated within the belt-shaped rope. ### Claim 9 (depends on 1) The rope arrangement according to claim 1, wherein the first coating portion forms a first outer side of the belt-shaped rope, and the second coating portion forms a second outer side of the belt-shaped rope, the second outer side facing the first outer side in thickness direction of the belt-shaped rope. ### Claim 10 (depends on 1) The rope arrangement according to claim 1, wherein the first coating portion and said second coating portion both include a polymer material. ### Claim 11 (depends on 1) The rope arrangement according to claim 1, wherein the first coating portion and the adjacent ones of the two or more load bearing members are surrounded by the second coating portion. ### Claim 12 (depends on 1) The rope arrangement according to claim 1, wherein a second outer side of the belt-shaped rope opposite to the outer side formed by the second coating portion, is contoured to have an uneven surface pattern. ### Claim 13 (depends on 1) A hoisting device comprising: the rope arrangement of claim 1, wherein the belt-shaped rope is connected with a load to be hoisted. ### Claim 14 A rope arrangement, comprising: a belt-shaped rope substantially larger in a width direction than a thickness direction thereof, the belt-shaped rope including, two or more load bearing members, and a coating embedding the two or more load bearing members therein, the two or more load bearing members oriented to extend parallel with a longitudinal direction of the belt-shaped rope such that a gap is formed in the width direction between adjacent ones of two or more load bearing members, the coating extending into the gap, the coating including, a first coating portion between the adjacent ones of the two or more load bearing members, the first coating portion including a first material, and a second coating portion forming an outer side of the belt-shaped rope facing the thickness direction, the second coating portion including a second material that is substantially softer than the first material; and a crowned rope wheel including a crowned circumferential surface such that end diameters thereof are smaller than a central diameter thereof, the crowned rope wheel having the belt-shaped rope passing therearound such that the second coating portion forming the outer side of the belt-shaped rope rests against the crowned circumferential surface of the crowned rope wheel, wherein the first coating portion and the adjacent ones of the two or more load bearing members are surrounded by the second coating portion.
